The Northrop YC-125A was developed in 1948 and intended for use as a tactical transport for rough, short fields.  It is the last tri-motor propeller driven aircraft to see service in the U.S. military.  By the time the C-125 was ready for production the jobs it had been intended to do were being done by helicopters and the C-123.  The Air Force decided that it had no flying job for the few C-125s that were built.  Most, like this one, went directly from the factory to technical schools for use as non-flying ground trainers.  After brief military careers most of the 23 C-125s built were sold to a Florida company which then resold them to airlines in Latin America.  Most were out of service by the mid-1960s.  Only two Raiders are known to exist, both in museums in the United States.
